SPECIFICATION forming part' of Letters Patent No. 492,574, dated February es, 1893.

Application led July 18, 1892.

To all whom tgmay concern:

Be it known that I, VILLIAM Il. DAYTON, a citizen of the United States, residing at Torrington, in the county of Litchfield and State of Connecticut, have invented an Improvement in Machinery for Swaging Rods and other Round Articles, of which the following is a specilication.

In an application of like date herewith, I have represented a swaging machine in which separate wires or blanks are fed into swaging dies, and these dies are brought nearer together or farther apart in the swaging operation in order to swage spokes for bicycle and other wheels, or other articles that are round and of -larger diameter at one place than at another.

In the present `invention I feed the wire into the swaging lnachine progressively from a reel, and the wire as it passes into the inachine is straightened and it is fed by rollers moved progressively and automatically, and the swaging dies are revolved continuously by a hollow shaft `carrying suchl dies, and these dies are controlled automatically so as to act closer togetherat one part than at another, and thereby vary the size offthe round article that is being swaged, and the swaged wire or rod passes on through the hollow revolving shaft carryingthe swaging dies, to a gage and cutting apparatus, whereby the spokes and other similar articles are cut oif in regular lengths, the operations being automatic and the parts are so .adj usted that any slight inequality in the size of the wire or any' wear in the parts can be compensated so that the finished or swaged wire is cut oi at the proper places to correspond with the reduced or enlarged port-ions of the wire as it is swaged.

In the drawings Figure l is a side elevation of the machine with one of the gears partially removed toshow the cams, the cutting die being in section. Fig. 2 is aplan view showing the feeding rolls and the actuating mechanismft'he swaging dies and the revolving shaft being removed for greater clearness, and Fig. 3 is a detached section of the swaging dies.

The swaging dies A are in a cross slot 1n the revolving shaft B, and laround such dies Serial No. 440.303. (No model.)

there are a circular range of rollers D within the stationary shell C that is supported byl the standard or frame C', 'and the tubular. bearing (l2 carries the revolving shaft D, and there are upon the shaft B a fly wheel Baud driving pulley Bzandloose pulley B3 by which the shaft B is revolved with/regularity, and an end movement is provided by which the l action of the swaging diesis regulated,so .6o that they are brought nearer together or farther apart, according to the sizeof the article' or the particu-lar part thereof that is being swaged, in my patent granted May l0, i892, wedges are shown for eecting this object and the end movement may act upon such wedges, or when the motion is given directly to the shaft, the rollers D may be inclined more or less, so that the dies are closed nearer together or farther apart according to the-7o relative position of the dies to the inclined surfacesof the rolls, and' with the object in view o fgiving the end motion, cam E upon the cross-shaft F lever l1, and a collar 15 which is between the 7`5 nuts 14 upon the revolving shaft li, as in my aforesaid application. The worm pinion 9 acts upon the wheel V upon the cross shaft F, so that the same is rotated at the desired speed, there being a driving pulley U upon 8o t'hecounter-shaft' T, and upon this-shaft F there are the cam-s for giving the movements hereinafter .de scribed,

The reel of wire is represented at J upon a suitable support, and such wire is drawn over and between the straighteners K, which straighteners may be of any suitable character; I have represented them as small rolls, and the feed rolls are represented in pairs. I prefer to use three pairs of feed rolls L L ,9o L2, and these are all geared together, so as to move irrthesproper direction and with uniformitj7 of speed`and one of the rollers receivesmo-tion from a gear wheel M upona shaft n, and this movement is' progressive, 95 there being a ratchet wheel N loose upon the shaft n and a pawl o upon the gear wheel KM and to the ratchet wheel N a reciprocating partial rotary movement is given by the connecting rod O to a lever P that is' acted upon roo in one direction by a cam p, and the spring r acts in the other direction, the shapeof the I provide a acting upon a cam p is such that motion is communicated thron gh the ratchet Wh e'el N, gear wh eel M and pawl o at the proper time and with the proper speed, so that the feed takes place as the dies are brought nearer together bythe end move; ment before described, so that the wire is fed at the proper speed during the reduction thereof bythe swaging dies, and when the proper end movement has been given and the article produced is to be cut olf, the feed is momentarily stop ed, and this is effected in this instance by the s ape of the cam p which allows the ratchet Wheel N to be rotated in such a direction thaty the pawl o runs over the teeth thereof and catches at the proper place for giving a fur ther progressive movement in feeding in the blank;

It will be understood that the wire as it is reduced by the swagng operation at the properplaces passes along through the hollow revolving shaft B, and at the rear end thereof a cutting apparatus of any suitable character' is provided;-I have shown this cutting apparatus as' consisting of a. stationary block R, anda shear S acting therewith, and this usually is lifted so that the wire or swaged arti cle passesalong through the block R' until it reaches the screw stop 16 which arrests the movement of the wire while -the shear S is brought down to cut 0E the wire.- S isactuated at the proper time by the cam t, lever wand connecting rod 11,and the parts are returned to their normal position by the spring w; and it is to be understood that the parts are so timed thatinswaging'an article such as a spoke for-a wheel, the dies are open after the swaged portionhas been completed,

and the. spoke that is to be cut olf reaches the screw stop 16g-and then' the cutting is effected while the feeding deviceis upon the return stroke and the rollers remain quiescent, and then the dies are closed to reduce the wire to the properextent and theV feed comes into action to carry the wire along While the body of thespoke -is being reduced to the proper-size; the swaging dies are then lallowed to 'open sufficiently for the wireto be fed along, and either not reduced or and the 'end of the wire,coming against the stop 16, the movement of the wire is arrested and the end spoke is'cut off as before described and the operations are repeated.

ln cases where the feed rolls are movedwith regularity 'so that the feed is continuous, the opening and closing of the dies and the cutting devices are so timed as to act properly upon the wire, and the cut can be'suffi- This shear only partially reduced,

ciently rapid not to cause the wiretobend by the momentary cutting operation.

1. The combination with the swaging dies and the mechanism for revolving and acting upon the same, of a wire straightening device, felcd rollers for supplying the wire' to the swaging dies, and automatic intermittent mechanism 'forfacting upon the feed, and a cutting mechanism brought into action while the feed is out of action, substantially as set forth.' l Y Y Y 2. The combination in a swaging machine, of swag'ing dies, a revolving shaft carrying the same, rollers for acting upon the swaging dies, adjusting mechanism acting endwise of `the revolving ,shaft for varying the opening and closing of the swaging dies, a straightening mechanism for acting upon the wire as it passes from areel, feeding rollsin'pairs geared together, between which the straight-A ened wire passes, automatic mechanism for moving the feeding rolls, the same-.acting intermittently, and a'cutter, a stopV for the end of the Wire` and mechanism for acting upon the cutter to sever the finished article during the time that the feed movementis arrested, substantially as set forth.

3, The combination with the swagin'g dies and the mechanism for revolving' and acting upon the same, of a wire straightening device, feed rollers for supplying the wire to the swaging dies, and automatic mechanism for acting upon the feed and a cutting mechanism brought into action while the feed is out of action, substantially as set forth.

4. The combination inapswaging machine,

of swaging dies, a revolving shaft carrying 95 the same, rollers for acting upon the swaging dies, adjusting lmechanism acting endwise'of the revolving shaft for varying the4 opening and closing` of the swaging diesa straightening mechanism for acting upon the wire as it passes from a reel, feeding rolls in pairs geared together, `between which the-straightened wire passes, moving the feeding rolls, and a cutter, a stop for the end of the Wire and mechanism for acting upon the cutter to sever the finished article during the time that the feed movement is arrested, substantially as set forth.
